What Invisalign Can Fix
Invisalign treats most common orthodontic problems: crowded teeth, gaps, and bite issues including overbite, underbite and crossbite. It handles the majority of adult cases well; very severe skeletal bite problems or the most complex movements may still need fixed braces or specialist input.
The short answer
- •Crowded teeth and gaps are bread-and-butter Invisalign cases.
- •Overbite, underbite and crossbite can often be corrected, sometimes with elastics.
- •Each condition has its own treatment page with the detail.
- •Very severe skeletal cases may need fixed braces or specialist referral.
- •A scan and ClinCheck confirm what is realistic for your teeth.
The common cases
Crowding (teeth overlapping for want of space) and spacing (visible gaps) are the most straightforward things Invisalign corrects, often within a Lite or moderate plan. Mild to moderate bite problems, where the upper and lower teeth do not meet correctly, are also routinely treated.
Bite correction sometimes uses buttons and elastics alongside the aligners to shift the arches into a better relationship. Your dentist explains whether your case needs this at the planning stage. Each condition is covered on its own treatment page.
Where it reaches its limits
Invisalign is powerful but not unlimited. The most severe skeletal discrepancies, large rotations on certain teeth, or cases needing significant jaw correction can sit beyond what aligners alone achieve, and an honest provider will say when fixed braces or a specialist orthodontist is the better route.
The only reliable way to know is an in-person exam and a 3D scan. A ClinCheck plan shows what the movements can realistically deliver before you commit to anything.
